Abstract

PURPOSE: To obtain the nonvolatile storage device of long life with equivalent performance in comparison with electonic switches through the sequential change- over of a plurality of nonvolatile memories for backup.
CONSTITUTION: If the write-in/readout from a nonvolatile storage device 3 to the backup memory 3a which stores the channel selection of TV receivers at power failure is repeated for a given number and the life of the memory 3a is gone by, the write-in to the memory 3a via a register 31 is not normal. Thus, the disagreement between the write-in data from the register 31 and the readout data from the memory 3a is detected at a control section 35, the address counter 34 is advanced and the memory 3a is changed over to the memory 3b, the content of the register 31 is written in the memory 3b and sequential backup is made with the change- over of the memory. Accordingly, the device 3 is the backup use of nonvolatile storage device almost the same longer life as electronic switches.
